الموضوع: نصيحه لماء الرادتير

لو معندكش تسريب ممكن عادي جدا تقعد ال2 بدون تزويد ميه.........ولو أحتجت تزود بتخلي معاك جركن فيه نسبة 30% ميه خضرا:70% ميه مقطرة...........العفو

يا جماعة الأفضل لو هتزود ميه على الميه الخضراء تكون مقطرة لأن مفيهاش أملاح - أنما الميه العادية سواء من الحنفية أو معدنية فيها املاح

أنا اظن ان الناس بتخاف تحط الميه المقطرة بتركيزها علشان بيبقى فيها مانع صدى وطبعا فى العربيات القديمة بيعمل كأنه مزيل للصدأ وبالتالى الرواسب ممكن تسد الدورة
أما بالنسبة للعربيات الجديدة معتقدش ان فيه مشكلة انك تحط جركن ميه خضراء 4 لتر كامل ولما تزود برضه تزود ميه خضراء .. بس أهم حاجة يكون نوع موثوق فيه

الميه الخضرا المركز لكامل دورة التبريد هاتجيب نتيجة عكسية وكمان هاتسخن العربية

I know that antifreeze prevents my engine’s cooling system from freezing in the winter, what else does antifreeze do for my engine’s cooling system?

Antifreeze (engine coolant) performs several functions in addition to providing freeze protection. Antifreeze contains chemicals that inhibit corrosion and scale formation in the engine and radiator. Antifreeze (engine coolant) provides protection against boiling in the summer. At one atmosphere pressure pure water boils at 212 °F (100 °C) but a 50/50 blend of water/ethylene glycol boils at 223 °F (106 °C).

How much water should I mix with my antifreeze?

If you mix antifreeze with distilled water at the ratio of one part antifreeze to one part water, you will have freeze protection down to –34°F and boil-over protection up to 265°F (if using 15 PSI pressure cap). Never use concentrated antifreeze in a cooling system without adding water. At least 40% of the mixture should be water.

Refer to freezing points of aqueous glycol solutions for the proper concentration levels of ethylene and propylene glycol.

If I buy concentrated antifreeze, can I get the proper water/glycol mixture using tap water?
Using “hard” water out of the tap can cause scaling in the engine. Tap water is purified for drinking by chlorination, which kills germs but can cause corrosion in the engine. Even if you carefully measure the amounts of tap water and antifreeze to get the right blend, using tap water is not a good idea. Tap water also contains dissolved oxygen, calcium, magnesium, and other contaminates besides chlorine and chlorides that can significantly degrade corrosion inhibitor performance.

If I buy concentrated antifreeze, how can I insure I get the proper water/glycol mixture for my climatic conditions? Do I need to mix it before I pour it in the radiator?

You cannot tell whether or not you have the proper water/glycol mixture just by looking at the antifreeze. A hydrometer uses floats to measure the specific gravity of the glycol/water mixture and indicate the amount of glycol. A refractometer measures the bending of light by the glycol/water mixture to determine the amount of glycol. Refractometers generally are more accurate than hydrometers. Measuring and mixing the water and antifreeze before adding them to the radiator is good practice. Mixing errors and the harmful effects of using tap water can be eliminated by using a pre-mixed antifreeze formulation like Arctic Blend®. The water used in Arctic Blend® antifreeze is de-ionized and won’t contribute to corrosion or scaling in cooling systems.

I live in Florida, what should the percent glycol be in the antifreeze I use? I will make an occasional trip to Cincinnati in the winter.

Antifreeze products do more than just provide freeze protection. They also contain corrosion inhibitors that protect the engine and radiator. Maintain antifreeze concentration at least a 50/50 mix of glycol/water to ensure proper corrosion protection regardless of where the vehicle is operated. A 60/40 glycol/water mix is preferred for colder climates found in northern US and in Canada.

What type of water should I use in my radiator?

Water quality is critical. Vehicle manufacturers recommend mixing de-ionized or distilled water with antifreeze. Do not use tap water, which may contain minerals that will corrode your cooling system and/or cause scale buildup. Do not use water softened with salts. The water used in Arctic Blend® antifreeze is de-ionized, which is chemically equivalent to distilled water. It has gone through EET’s multi-step decontamination and desalting processes and won’t contribute to corrosion or scaling in cooling systems.

What happens if I use too much antifreeze or water?

Using too much antifreeze or water in your engine coolant can harm your vehicle. Antifreeze concentrations higher than recommended levels can cause problems including corrosion, water pump failure, and increased engine wear. Increasing the concentration of ethylene glycol above 60% actually hurts the engine’s freezing and overheating protection. More is not always better!

Adding too much water to the cooling system lowers the concentration of corrosion inhibitor and antifreeze and results in decreased protection against corrosion and freezing
